Young emerged as a first-half substitute for the injured Anthony Martial but began trending on Twitter over his poor crossing on the right flank and for spurning a decent chance at 0-0.

Despite certain United fans' qualms, Mourinho was pleased with Young's 'positivity and determination' in United's third successive loss.

"I have this capacity of balance," Mourinho told MUTV. "Balance is, for me, not running around the pitch when we were winning a couple of matches and nobody sees now me being too depressed. I'm sad. Obviously, I'm sad but, as I was telling the players, there is only one way.

"At 10:30 in the morning, we have a training session and we have to be there. They have to work, they have to show themselves with a certain kind of attitude towards negative moments. I show them, as an example, Ashley Young who was, in my opinion, phenomenal with his attitude, positivity and determination.

"We need positive people to give us a positive feeling because, next time these boys are going onto a football pitch, they are going to feel, obviously as normal human beings, the weight of the defeats."
